Combination effect of epigenetic regulation and ionizing radiation in colorectal cancer cells. [PDF]

PLoS ONE, 2014
Exposure of cells to ionizing radiation (IR) induces, not only, activation of multiple signaling pathways that play critical roles in cell fate determination, but also alteration of molecular pathways involved in cell death or survival.

A Systematic Mapping Review of Core Outcome Reporting in Surgical Research for Oesophageal Cancer

Journal of Surgical Oncology, EarlyView.
ABSTRACT Oesophageal carcinoma is a rising global health burden, with surgical resection and perioperative chemotherapy forming the cornerstone of curative treatment. However, uncertainty persists regarding the optimal surgical approach, partly due to heterogeneity in outcome reporting, which hinders data synthesis and evidence‐based decision‐making ...

Types of Pain in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Pain affects up to 87% of people with multiple system atrophy (MSA), but it remains unclear which types of pain contribute most to the overall burden. Objective To estimate the frequency of different types of pain in MSA individuals.

Single‐egg comet assay: A protocol to quantify DNA damage in natural bioarchives

Methods in Ecology and Evolution
The comet assay (CA), originally developed as toxicity test, quantifies DNA integrity from DNA distribution across an electric field. Compromised DNA moves across electric fields faster than intact DNA strands, leaving quantifiable signatures that ...

Rapid actin monomer–insensitive depolymerization of Listeria actin comet tails by cofilin, coronin, and Aip1

Journal of Cell Biology, 2006
Actin filaments in cells depolymerize rapidly despite the presence of high concentrations of polymerizable G actin. Cofilin is recognized as a key regulator that promotes actin depolymerization.

A Dormant Captured Oort Cloud Comet Awakens: (18916) 2000 OG44

The Astrophysical Journal Letters
We report the discovery of activity emanating from (18916) 2000 OG _44 (alternately designated 1977 SD), a minor planet previously reported to be both an extinct comet and an asteroid on a cometary orbit. We observed 2000 OG _44 with a thin tail oriented

Artifacts in metallography: mechanical damage during sample preparation. Part 2. Artifacts introduced by grinding and polishing

Литьë и металлургия
This study demonstrates the appearance of ground surfaces of ferrous and non-ferrous metal alloys when the defective layer from sectioning is incompletely removed. The defects resulting from insufficient grinding and polishing at various stages of sample

Insulin Stimulates Actin Comet Tails on Intracellular GLUT4-containing Compartments in Differentiated 3T3L1 Adipocytes* 210

Journal of Biological Chemistry, 2001
Incubation of isolated GLUT4-containing vesicles with Xenopus oocyte extracts resulted in a guanosine 5′-[γ-thio]triphosphate (GTPγS) and sodium orthovanadate stimulation of actin comet tails. The in vitro actin-based GLUT4 vesicle motility was inhibited
